The Senix ToughSonic ultrasonic sensors measure level and distance through the air using ultrasonic sound waves. They provide fast, reliable non-contact distance measurements for up to 50 feet (15.2m). Sensors feature solid state electronics, ruggedised piezoelectric tranducers, high quality housings and full epoxy potting for protection in the harshest environments. The Senix TSPC sensors are housed in a marine grade 316 stainless steel housing. The Senix ToughSonic CHEM sensors are in a Kynar PVDF housing for protection against solvents, acids and bases, allowing the LVL sensors to be full immersed in harsh chemicals without damage. Both models will provide 4-20mA/0-10V analogue outputs, NPN/PNP switching outputs and serial output. The SenixView software provides adjustment, viewing, analysis, maintenance and cloning without recalibration of both sensors and the TSPC units can be programmed using the push button on each sensor.
